| Abstract: | Cathode material LiaNi0.9Co0.1Fe0.03 O2 was synthesized by solid - state reaction after precursor material was synthesized by eo -precipitation method. It was proved that the sample has good electrochemical properties when starting materials were pre- treated. Electrochemical tests showed that the first specific charged and discharged eapaeities were 168.9 and 167.1 mAh · g^ -1. Current efficiency was 98.9%. |
